这个乘以50%的概率有点不是很理解。

问题如下:

Company M has a four-year project with an expansion option, which depends on the demand at the end of the 1st year. Whether demand is -high- or -low- in Years 1–4 will be determined during the first year. The probabilities of -high- or -low- demand are equal. The cost of capital is 12%. We should notice that the expansion option will not exist if the initial investment is not made. The detailed information of the project is given in the following tables.

The initial project:

Additional cash flows with the optional expansion project:

The NPV of the initial project without the real option is given to be -13.32, what’s the NPV of project including the expansion option?

选项:

A.

-$6.11 million

B.

$6.37 million

C.

$19.69 million

解释:

B is correct.

考点:Evaluating Projects with Real Options

解析:t=1如果是高需求,NPVexpansion = -100 + t=13601.12t\sum_{t=1}^3\frac{60}{1.12^t}= $44.11 million,此时扩张期权会执行如果是低需求,NPVexpansion = -100 +t=13301.12t\sum_{t=1}^3\frac{30}{1.12^t} = -$27.95 million,此时扩张期权不会执行

t=0,Expected NPVexpansion = 0.5*44.11/1.12 = $19.69 million

因此在考虑了扩张期权之后的NPV = -13.32 + 19.69 = $6.37 million

老师,在t1的时候进行比较,看NPV大于0的话,那我们就会行权,那么我们这时候只有在60的时候会行权,在30的时候就不行权了。

那为什么不就是把在60的t1=44.11/1.12,折现到0时间点,再加上原来的NPV就好了,而是还要再乘以0.5呢?

这个0.5我不是很理解,麻烦老师解释一下。谢谢!

嗨,努力学习的PZer你好:


因为可选的扩张项目,第二年到第四年的现金流为 60 的概率,是 50%,而不是 100%

同学所理解的做法,对应的题目背景就不是实务期权项目了,是下面的背景

现在确定要做一个扩张项目,在第一年追加投资 100,第二年到第四年的现金流,100% 确定能多回收 60。问原有项目加上扩张项目,总共的 NPV 是多少

----------------------------------------------
加油吧,让我们一起遇见更好的自己!
